Caller said he's from UPS. Wondering if my business will be open Fri. July 3rd to accept deliveries. I asked what he had for me; he said he had nothing, he's just checking local business's schedules. He didn't identify himself, but reverse lookup did show UPS as the phone number owner. I've had drivers ask about my holiday weekend schedule, but never got a direct phone inquiry like this. Just kind of weird.
The phone number belongs to UPS? Now, how about the caller? As you see the second answer is not as clear as the first, since caller ID is so easily faked. You can NEVER assume the caller is who they say they are. Never give out information on a call you did not make.
